Probably just someone who's fun or easy to draw. Unless she suddenly decides to sprout superpowers, helps free Jenny, or has a Cluster-proof gadget under that coat I will pay her no further mind. Not as if we don't have a Bell with a bomb with whom to contend here.
Where's Monkey? And also Perry. I think just a scrollling "Curse you Perry the--" across the windows would be hilarious. But not anymore, now that I've mentioned it, because sometimes humour takes the element of suprise, dash it all.

Oh lookie, it's the Beak. But honestly, you know it's just a spot appearance if some sort of gadget isn't involved at a science fair.
